K. E. Tsiolkovsky claimed that he developed the theory of rocket science only as an application to his philosophical research. He wrote more than 400 works, which are little known to the general reader due to their many years of silence. This book is an attempt to break through the “conspiracy of silence” around the philosophy of the Russian space seer, a student of the Russian philosopher N. N. Fedorov, the discoverer and solver of a complex of problems posed to human civilization by the beginning of the “space age.” New thinking is impossible without exposing “ordinary consciousness”, without searching for the meaning of life beyond everyday life in the unity of the populated cosmos. The book’s text has been translated from the original language using an artificial intelligence system. In most cases, the translation is accurate and clear, but occasionally there may be incorrect phrasing or individual words left untranslated.
